Any simple methods for calculating planes from surface normals?

thanks

Along with the normal, You also need to know the position of the surface.

Ax + By + Cz + D = 0

So you just replace A = nx, B = ny, C = nz where n mean normal component, and you replace x,y,z by the position and you calculate D.

This gives you the full plane equation
